With a thumbs up from Artis Zoo Director Haig Balian, demolition of one of the oldest structures at the Amsterdam institution began. The old animal cages that houses the big cats stood since the zoo's creation in 1838.

"The gallery dates back to the 19th century, a time when other views in the areas of animal welfare, architecture and landscaping prevailed. These views are as outdated as the building itself," Balian said. "The demolition of this property is one of the milestones in our renewal process," he noted in a final farewell to the "old Artis."

Renovations at Artis include the opening of the Micropia microbe museum, more space for animals and plants, and further education opportunities. The renewal began about 12 years ago, with more focus on the balance between man and nature, the zoo said.

Artis hopes to grow into a leading institute within this field. The zoo has also pinned hopes that they will better fulfill their social responsibilities.
